摘要：
The invention relates to a method for the chemical looping combustion of a solid hydrocarbon feedstock, in which: particles of oxygen-carrying material originating from a reduction zone (RO) are brought into contact with a flow of oxidising gas in a reactive oxidation zone (R1); and the fly ash, the fines and the particles of oxygen carrying material in the mixture originating from zone R1 are separated in a diluted-phase separation zone (S2), the driving force required for diluted-phase elutriation in S2 being provided by the flow of oxidising gas from the reactive oxidation zone (R1). Optionally, enhanced separation is performed in a dust removal zone (S4) and, optionally, subsequently in a dense-phase elutriation separation zone (S5). The invention also relates to a chemical looping combustion facility that can be used to perform the aforementioned method.
